OpenJDK: use of unprotected sname in Kerberos client (Libraries, 8178794)

It was discovered that the Kerberos client implementation in the Libraries component of OpenJDK used the sname field from the plain text part rather than encrypted part of the KDC reply message. A man-in-the-middle attacker could possibly use this flaw to impersonate Kerberos services to Java...

Chinese Quantum Satellite Sends First ‘Unhackable’ Data to Earth

In what appears to be the world's first quantum satellite transmission, China has successfully sent an "unbreakable" code over a long distance from an orbiting satellite to the Earth, achieving a milestone in the next generation encryption based on "quantum cryptography." In August last year, Chi...
